Answer:
Step-by-step explanation:
The slope formula is used to calculate the slope if you are given two points. Remember that slope is defined as rise/run. Which translates to the rise divided by the run. The slope formula will allow us to take the change in the rise and divide by the change in the run.
Answer:
Step-by-step explanation:
Let the boy's present age be x.
Let his dad's present name be y.
Last year, his dad was 8 times as old as him. Subtract one year from each their ages and multiply the son's age by 8:
(y - 1) = 8(x - 1) ______ (1)
Now, his dad's age is the square of his age:
y = _________(2)
From (1):
y = 8x - 8 + 1
y = 8x -7
Put this in (2):
This problem has been represented in the form of a quadratic equation.

Answer:
Step-by-step explanation:
The -intercept of a line is the value when . In the equation , we can solve for its equation when we plug in .
Solving for when :
.
So the -intercept of the equation is .
To find what equation has the same -intercept, we can do the same process for each equations given by the choices. However, I can see that the equation, , has the -intercept. If in doubt, you can check for the solution below or solve each equations for yourself.
Solving for when :
